According to WuSay, Brazilian congressman Eros Biondini proposed a bill to establish a "Bitcoin Strategic Sovereign Reserve" (RESBit) to allocate up to 5% of international reserves to Bitcoin.

The move is aimed at diversifying national assets and responding to exchange rate fluctuations and geopolitical risks. The bill requires that reserve management follow the principle of transparency and adopt high-security storage methods such as cold wallets.

The central bank and the Ministry of Finance will be jointly responsible for management and regular disclosure reports. The proposal also plans to support the development of blockchain technology to provide reserve support for the future digital Brazilian real (Real Digital).
